Welch Boltimate is a core-shell material with a 1.7 μm diameter non-porous solid core, and a 0.5 μm porous outer shell. Boltimate can deliver speed and efficiency rivaling UHPLC, using conventional HPLC systems at much lower back pressure.

Specialized core-shell design allows for greater speed and efficiency.

Highlights

  • Achieves efficiency similar to sub-2 μm materials (~200000 p/m)
  • High speed and high resolution
  • Compatible with both HPLC and UHPLC systems
  • Operates at low pressure, but is stable up to 600bar (8700 psi)

Details

C18
Conventional C18 (USP L1) phase. Excellent resolution and lifetime for acids, bases, and neutrals

Phenyl-Hexyl
Alternative selectivity for phenyl groups (USP L11)

EXT-C18
C18 (USP L1) phase with modified organic/inorganic layer for extended pH range: 1.5 – 12

EXT-PFP
Alternate selectivity (USP L43) for halogenated compounds and polar analytes, pH 1.5 – 12

HILIC
Unbonded silica (USP L3), retains and separates polar analytes by hydrophilic interaction

LP-C18
C18 (USP L1) for optimal peak shape and resolution at low pH: 1.0 – 8.5
